I gonna be as fair about this as Magnus has been about his new cam. Not even on the same level. though. :D So:
As some of you know, I have been against going to a 3 inch I-pipe. After so many difficulties in finding a 2.5 or 2.75, I decided to go with the 3-inch dynomax (3" O.D., 2.75" I.D.). Well, I finally got it put on along with a catco 2.5" cat, dynomax 2.5" in/out super-turbo muffler and hooker dual 2.5" inlet 3" outlet quad tips. Here's my honest opinion:
If torque is being lost from going to a 3 inch (and logic dictates that it should be), then it is not worth talking about. The sound is outstanding: deep and robust. No rice whatsoever. I can't wait to see what muffler break-in brings to this system. You can now tell that the engine was struggling with the restrictive exhaust. Acceleration is smooth and continuous; overall engine operation is less jerky. Sound from giving the car moderate to heavy throttle is WONDERFUL!
As far as labor, I'm sure I got bent over on this one. Let's just say it wasn't 100 bucks or less compared to everyone else. I will say that the shop did an outstanding job. They took their time and fabricated necessary pieces. They even cut the o2 bung from the old cat and welded it into my new pipe. They relocated my cat, so the two 90 degree mandrel bends I originally bought for a custom s-pipe became part of my tailpipes. I now have a 3-inch mandrel bent catback without the added curve of the s-pipe. Pipe goes straight down from the converter, makes short 90 degree bend to the left, then straight back to the pipe that goes over the axle. The part numbers I ordered are 42273 and 45593. You have to have both pipes. Shortdog273 turned me on to this, so much props to him. An interesting tidbit; after 45 miles, I still have no SES light. I'll update this post if it ever comes on.
I have to admit that I was really embarrassed by the tone of my car with the dual outlet muffler from the muffler shop. If a car revved at me, I just gave them the nod to let them know I wanted to race. Now I can rev with pride. :D
